Hemipelvectomy and Hip Disarticulation

While less than 2% of amputees have a hemipelvectomy or hip disarticulation amputation, P&O Care is specially equipped to help these patients. These levels of lower extremity amputation require expert prosthetic care due to the loss of three joints: the hip, knee and ankle. The complexity of a hemipelvectomy or hip disarticulation prosthesis demands the highest levels of experience, dedication and compassion. We believe in relationships that matter and devices that fit.


Often the result of a traumatic injury or cancer, the hemipelvectomy amputation involves the removal of half of the pelvis and all lower extremity structures on the same side of the body.

Hip Disarticulation

A hip disarticulation involves the complete removal of lower extremity from the hip joint. A prosthetic hip, knee and foot are used to restore function.

A hemipelvectomy/hip disarticulation prosthesis can be quite complex The loss of the hip, knee and ankle require specialized components to restore function and mobility. We want to help you understand how each of these moving parts work together, simply click on the name to reveal more information.

Often referred to as a “bucket” design, this type of socket encapsulates the remaining tissue and is designed to support surrounding structures.

There are several styles of hip joints, from the single axis joints (forward and backward movement) to 3 dimensional joints, much like the ball and socket design of the anatomical hip, allowing movement in multiple planes (forward and backward and rotation side to side). The hip joints work together with the prosthetic knee and foot to efficiently aid the user.

The pylon is the metal component that connects the hip joint to the knee joint.

The rotator allows for 360 degrees of rotation below the component at the push of a button. This device helps patients get in and out of cars, tie shoes and get dressed with ease, by allowing the lower half of the prosthesis to be rotated and crossed over the other leg while sitting. The rotator safely locks into the correct position for normal walking. Ask your prosthetist if you have space to add the rotator component to your prosthesis.

Prosthetic knees are designed to replicate the bending or flexion of the anatomical knee joint. From advanced computer controlled components to simple locking joints, the prosthetic knee works together with the hip joint to achieve a smooth gait pattern. The choices in prosthetic knees are similar for nearly all lower extremity prosthetics. Read more about prosthetic knees here.

The pylon is the metal component that connects the knee to the prosthetic foot.

The choices in prosthetic feet are similar for most levels of lower extremity prosthetics. Read more about prosthetic feet here.

A custom shaped foam covering can be made to cover pylon and knee allowing the prosthesis to look similar to your sound side limb and protect the components from dust, debris and outside elements. Covering is usually completed when the prosthetist, patient and medical team are pleased with the fit, comfort and walking mechanics with your prosthesis, which is typically 2-3 weeks after delivery.

Resource Center

Our resource center is a great place to learn more about the most complex prosthetic components. We want you to be informed and empowered about your prosthetic future. You have more options than you think, we’ll show you.

Sockets and Suspension

Similar to other levels of lower extremity amputation, the “socket” is the custom made rigid frame designed to support the user’s body weight and is the main attachment point of the prosthetic components. Due to the removal of the hip and surrounding structures, the sockets and suspension techniques are slightly different at the hemipelvectomy and hip disarticulation levels, and can be quite complex. Therefore, your practitioner will fully discuss the fitting process, type of suspension and specific socket design on an individual basis. Lightweight materials, advancements in socket design hip joint technology have enabled both hemipelvectomy and hemicorporectomy amputees to walk with more security, comfort and confidence.
